I l KEROSENE-LAMP.

Be it known that I, BERNARD F. Ronmuo a citizen of the United States of America,

residing at San Diego; in the county'of San Diego and State of California, have invented certain new and useful Improvements in 'Kerosene-Lamps, of which the following is a-specification.

"This invention relates ,to lamps and more particularly to that class of kerosene lamps mploylng an incandescent mantle, the ob jeet of the invention being to rovide im- .proved"means in a lamp of tlns character for controlling the air supply to the flame, said fair supply being so controlled that the proper-amount of air 'is.delivere d whether the wick be turned hi h or low.-

A=further object the invention is the provision of an improved mant le support and flame spreader.

A- fur her'.object of the invention is the provision of improved means for holding thech'imney and mantle in an elevated p0 sition while the lamp is being lighted.

Further objects and advantages of'the invention will "be set forth injthe detailed description which now followsf In the accompanying drawing, Figure l is a-vertical section of a lamp constructed in accordance with the invention, Fig. 2 is a side elevation of said lamp, Fig. 3 is a versition the parts Figg is the lamp with the chimney elevating means shown in dotted lines, Fig. 5 is a perspective view of the chimney and mantle clevatingmechanism, Fi '6 is a perspective view of a erto rated ring hereinafter described, and, ig. 7 isarspeetive view of a mantle support lieul :section showing the occ'u y when the lamp is urnmg,

and ame spreader hereinafter describe Like. numerals designate corresponding parts'in all of the figures of the drawing.

By referring. to the drawing, it will be seen that this lamp comprises the usual bowl 5, an inner wick tube 6 which also serves as an air duct, and an outer wick tube 7. The wick 8travels between the inner and outer .wiek. tubes. As is clearly illustrated in Fig.

lythezouterlwick tube is bent to form a cuplike member 9 which is threaded at 10 to ads t it who screwed into the bowl 5. A wick contrdlling'device which has been iudicated in a general way at 11, serves to raise and lower the wick as desired. This wicknontrolling device is not novel. It

forms no art of the resent invention and consequent y w1l1 not e described in detail.

One of the most important features ofthe V present invention is the perforated ring '12 shown in Figs. 1, 3, and 6. This ring is insorted in the upper end of the inner wick tube 6 and is pre erably held against slidin down inside of said wick tube by an integra rib 13 formed upon said wick tube. It is of course apparent that this ring may be held in position in a number of ways and it is to be understood that the invention is not limited to the specific manner of holding this ring in position. If the'proper proportion of air be supplied to a kerosene burner of the character shown, a clear blue flame will result. If too much air be supplied, the result is a red and smoky flame which speedily coats the mantle with soot. The rforated ring herein shown and describe is so proportioned and-arranged as to supply just exactly the right amount of air to the burner at all times, whether the wick be turned high or low. As is clearly shown in Fig. 6, the perforations in the ring 12 are more numerous in the u iper portion of the ring than they are in the ower portion thereof. Consequently, when the wick is turned low it re ceives less air than when it is turned higher. the result of which is to. su iply just the right amount of air needed at all times. The importance of this will be apparent when itis reflected that if the right proportion of'air is not an plied to the burner, a red and sooty flame wi 1 result. As has been before stated this will speedily coat themantle .withs otand the coating of the mantle with soot 'll in turn prevent the passage of the gases generated at the burner, through the mantle. thereby rendering the lamp totally useless.

The cup-like member 9 earrics'guide tubes 14 in which rods or smaller tubes 15 slide. These rods or tubes 15 are connected to cars 16 of a ring 17, said ring in turn supporting a chimney carrying cap 18. cup-like flame s rea er 19 has a socket 20 formed therein or the reception of a mantle supporting rod. 2i, The nantle 22 is supported by this red and incloses the [lame spreader. The cup-like flame spreader earries outward] Y and downwardly projecting arms 23 \vhici engage the edge 24' of the chimney carrying cup 18 The cup 1%) also carries inwardly and upwardly directed arms 2.; which engage the mantle supporting rod 91, the lower end at: said rodentering the socket. 20. J ournaled in a b ing 26 of the cup-like member 9 is a shaft 2 to which rotation may be im arted by a humb iece 28. Rigidly secure to the inner e d 0 this shaft 27, is a crank'29 which has ivoted link connection 30 with the ring 17. strap 31 carries a pin 32, said pin serving as a stop for the crank 29 as Wlll be h reinafter set forth. \Vhen it is desired to light the lamp, the shaft 27 is rotated to row the crank 29 u wardly and over its con r. This raises the rin 17 and the parts carr ed thereby, it bcin ',apparent that said parts include the c 1 mney and mantle. This permits free acc s to the wick for the purpose of lighting th lamp. When the crank 29 is thrown slight y over its vertical center, it strikes the pin 32 and downward movement of the ring 17 is thereby prevented. The rin 17 will therefore be held in an elevated ;position until the crank 29 is swung back over its vertical center. In Fig. 1, the parts have been illustrated in the position which they lie when the shaft 27 has been iiiirtially rotated. to elevate the chamber cirrrying ring 1K. The position in which the arts lie when the lamp is burning has been illustrated in F ig. 3. During the vertical movement of the chimneyamd mantle, the guide members 14. and 15 hold the parts in proper vertical alinemcnt.

From the foregoing description, it will be seen that simple and eflicient means are herein-provided for accom lishing the objects of the invention, but while the elements shown and. described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is:

1. In a device of the character described, the combination with im inner wick tube, an outer wick tube. of a -perforate ring carried by said inner. .cktube at the upper end thereof, a chimney carrying cap, a flame I spreader supported from said cap, and a mantle support mounted upon -;said flame spreader. V

2. Ina device of the character described, the combination with a chimiiey bearing cap, of a cup-like flame spreader, supporting arms extending from the flame spreader to said cap, there being asocket formed in said cap a centrally disposed mantle supporting rod ada ted to enter said socket, and arms ex-v ten ing from said flame spreader to said rod.

3. A lamp of the character described, comprising an inner wick tube and an outer wick tube, a removable, perforated ringseatedain the upper end of the inner wick tube "la chimney carrying cap, a centrally disposed flame spreader, and spaced arms extending from said flame spreader to the upper edge of the chimney carr ing cap.

4. A lamp of the prising an inner wick tube and an outer wick tube, a removable, perforated ring seated in the upper end of the inner wick tube, a chimney carrying ca a. centrally disposed flame spreader, 5 ac arms extending from said flame sprea er to the upper edge of the chimney/carrying cap, and a centrally disposed mantle support projecting upwardly from said flame spreader. i

5. A lamp of the character described, comprising an inner wick tube and an outer wick tube, a removable, fperforated rin seated in the upper end o the inner wicr tube, a chimney carrying ca a centrally disposed flame s reader,space -arms extending from said ame spreader to the upper ed e of the chimney carrying" cap,a centra ly disposed mantle support projecting upwardly from said flame spreader, and inwardly and upwardly directed arms extending from the edge of the flame spreader and engaging and bracing said mantle suport. P In testimony whereof I- aflix in presence of two witnesses.
